![]() If a causal link needs to be established, then further analysis to control or account for other potential variables effects needs to be performed, in order to rule out other possible explanations. Plotting Multiple Scatter Plots in Matplotlib. ![]() I have included plt.figure(figsize(20,20)) but it doesnt affect the size. It is possible that the observed relationship is driven by some third variable that affects both of the plotted variables, that the causal link is reversed, or that the pattern is simply coincidental.įor example, it would be wrong to look at city statistics for the amount of green space they have and the number of crimes committed and conclude that one causes the other, this can ignore the fact that larger cities with more people will tend to have more of both, and that they are simply correlated through that and other factors. Im unable to resize the graph in my matplotlib scatter plot. This gives rise to the common phrase in statistics that correlation does not imply causation. When creating plots using Matplotlib, you get a default figure size of 6.4 for the width and 4.8 for the height (in inches). F gcf() Size F.getsizeinches() F. Simply because we observe a relationship between two variables in a scatter plot, it does not mean that changes in one variable are responsible for changes in the other. import matplotlib.pyplot as plt import numpy as np Fixing random state for reproducibility np.ed(19680801) N 50 x np.random.rand(N) y np.random.rand(N) colors np.random. This is not so much an issue with creating a scatter plot as it is an issue with its interpretation.
